ULTRASONIC WELD ANALYSIS FOR ORTHOTROPIC STEEL DECKING SYSTEMS IN BRIDGES

摘要

A system provides for the calculation of the penetration depth of a weld in an orthotropic steel decking system. Weld scan section data is accessed and each scan section along the weld seam is processed to find the amount of penetration as a percentage of the thickness of the rib leg metal at the weld location. The amount of penetration is calculated by finding ultrasonic reflections recorded as voxels that have the greatest magnitude within an area of contiguous magnitudes and then determining the location of those voxels relative to the weld geometry and distance along the thickness of the rib leg steel. A report for each section scan and the entire weld seam may be generated for review by a weld inspector that allows for spot inspections of specified areas along the weld seam for possible weld remediation.
